  • How is textile wastewater treated?
  • Textile wastewater is a combination of various chemicals and different types of dyes and has a salty nature. In this study, an SBR (sequencing batch reactor) was used to treat synthetic and real textile wastewaters in a 24 h cycle time. Remazol Brilliant Blue R, a reactive dye, was used as the model dye.
  • Does activated sludge remove dye from textile wastewater?
  • With regard to the salty nature of textile wastewater, SBR was selected as the treatment system in the present study, the main purpose of which was to investigate the ability of the aerobic microorganisms of the activated sludge to remove dye from textile wastewater containing a high concentration of salts.
  • What is the Salt Range of textile wastewater?
  • According to different resources, salt range of textile wastewater is varied between 1000 and 10,000 mg/L ( Salvadó et al., 2001, Yurtsever et al., 2016) and the textile industry interns almost 0.2 million tons of salts in the environment per year ( Soares et al., 2017 ).
  • Can activated sludge withstand saline shock?
  • The results of a research related to saline shock on activated sludge indicated that the tolerance threshold in activated sludge microorganisms is different when they encounter saline wastewater; some of them resist salt concentrations up to 5000 mg/L and some of them up to 10,000 mg/L ( Salvadó et al., 2001 ).
